| 摘 要： | 在CITYgreen模型支持下，以1994年与2004年的杭州市Landset TM数据提取的土地利用信息与绿地分布数据为基础,对杭州市人工绿地、人工林地与天然林地的生态服务价值进行估算和对比分析，研究杭州市土地利用变化和经济发展状况对其的影响.结果表明,10年间，杭州市绿地虽然减少了20.4%，但绿地生态服务价值增加了1.68×109元，绿地生态服务价值与杭州市GDP年度增长率分别为111.92%和5.32%，适宜的土地利用调整有效地协调了城市经济发展与城市生态功能的关系，实现了土地利用的生态服务高效能.

| Abstract: | Based on the Landset TM information of land use/cover change and greenbelt distribution in Hangzhou city in 1994 and 2004,and by using CITYgreen model,this paper estimated the eco-service value of urban greenbelt in the city under the effects of land use change and economic development.The results showed that in the 10 years from 1994 to 2004,the greenbelt area in the city decreased by 20.4%,while its eco-service value increased by 168 million yuan.The annual increment of greenbelt eco-service value and GDP was 111.92% and 5.32%,respectively.Suitable adjustment of land use pattern in the city harmonized the relationships between urban economic development and urban eco-function,and achieved higher eco-service efficiency of land utilization. |
